Abstract: A curable organopolysiloxane composition remains fluid when held under seal in the dark, rapidly forms a nonfluid tacky mass when exposed to high energy radiation, such as ultraviolet or electron beam radiation, and subsequently continues to cure through an atmospheric moisture-mediated reaction to yield an elastic material.  The curable organopolysiloxane composition with a viscosity at 25°C not exceeding 3,000 Pa.s, comprises the product obtained by mixing an alkenyl-functional silicone resin, a mercapto-containing organopolysiloxane that contains siloxy units functionalized with both mercapto and Si-bonded alkoxy, and does not contain alkenyl, and a condensation reaction-accelerating catalyst.  The curable organopolysiloxane composition is used in a method for making an assembly by bonding a substrate and an adherend by coating the substrate with the composition, irradiating the coated substrate with high energy radiation, bringing the adherend into contact with the irradiated surface, and thereafter holding the assembly in a moisture-containing atmosphere.

Title: Electrode for a plasma arc torch
Inventor: LUO LIFENG
IPC: B23K10/00
Filed: 1995-07-11
Abstract: An insert securely disposed in a bottom end of an electrode has an exposed emission surface shaped to define a recess in the insert, wherein the recess is initially dimensioned as a function of the operating current level of the torch, the diameter of the insert, and the plasma gas flow pattern in the torch. The electrode has an elongated body formed of a high thermal conductivity material such as copper, and a bore disposed in the bottom end of the body along a central axis. The insert is formed of a high thermionic emissivity material, such as hafnium, and securely disposed in the bore with the emission surface exposed. The emission surface may be initially shaped by removing a predetermined amount of the high thermionic emissivity material from the insert to define a generally concave recess, a generally cylindrical recess or other shapes. When used in a torch, the electrode provides for reduced deposition of the high thermionic emissivity material on the nozzle, thereby reducing nozzle wear in the torch.

Title: A muting device for stringed musical instruments
Inventor: KITTLE JOHN
IPC: G10D3/04
Filed: 1997-02-21
Abstract: A muting device for a stringed musical instrument comprising a hollow rectangular body with a lug projecting from said body adapted to engage the top surface of the bridge of a stringed musical instrument. The muting device is fixed to the stringed musical instrument by the means of parallel concave grooves in each side of the muting device which are adapted to receive the strings of the musical instrument. The width of the muting device is slightly greater than the width between the strings of the musical instrument and therefore the muting device is firmly fixed to the instrument. In an engaged position, the muting device is slid up the strings so that the lug engages the top of the bridge. The muting device is adapted to transmit tensile forces inherent in the strings of the musical instrument through the muting device to the lug and subsequently to the top surface of the bridge thus enhancing the muting effect of the device while maintaining its mass very low.
